Gold Standard 100% Casein by Optimum Nutrition is a slow-digesting protein powder designed to deliver sustained amino acid support, making it ideal for use between meals, after training, or before bed. Each serving provides 24 grams of premium micellar casein, supplying the body with a steady stream of protein to help build and maintain muscle over several hours. With nearly 5 grams of naturally occurring BCAAs, it supports endurance and recovery while promoting satiety.
Low in sugar and fat, and containing fewer than 120 calories per serve, this formula suits those aiming to manage macros while ensuring consistent muscle repair. Gold Standard 100% Casein is also Informed-Choice certified, meaning it's regularly tested for banned substances. Available in multiple flavors and serving sizes, it sets the benchmark for nighttime and extended-release protein support.
